No new blocks produced by sequencer
  • Resolved
    Resolved

    The sequencer has recovered and is producing new blocks.

  • Identified
    Identified

    A sequencer stall has led to the sequencer needing to resync from an earlier snapshot of the chain. This has led to no new blocks being produced while the sequencers catch up.

Unichain Sepolia Safe Head Stall
  • Resolved
    Resolved
    This incident has been resolved.
  • Identified
    Identified

    The op-node rejected some batches from the batcher and the safe head stalled out for 12 hours. Consequently, a re-org occurred. The batcher is correctly posting again.

Node Syncing Outage
  • Resolved
    Resolved

    Due to an issue with the batcher, there was a deep reorg. Unichain Sepolia has recovered at this time. Users who are running full (non-archive) nodes will need to re-sync the chain.

Active Sequencer stalled
  • Resolved
    Resolved

    This incident has been resolved. Batcher operation is restored, L2 blocks are being produced and safe head latency is at normal rates.

  • Identified
    Identified

    At 12:00 AM PST, our active sequencer stalled and failed to derive or produce any further blocks. We have identified the issue as being related to the communication between op-geth and op-node over the Auth RPC port. We have mitigated this issue by restarted the sequencing nodes.
